TIINA186A4QDBVRQ1

Overview

The INA186A4QDBVRQ1 is an automotive-qualified, high-precision current sense amplifier designed for low-side and high-side monitoring. It features a high gain of 200 V/V and a low input offset voltage of 3 uV, enabling accurate current measurements using small shunt resistors to minimize power loss. This AEC-Q100 qualified device is optimized for efficiency with a very low supply current of 48 uA.

Why Choose This Part

The device offers exceptional precision with a 1 percent maximum gain error and ultra-low input bias current of 500 pA, which allows the use of large input filters without compromising accuracy. Its rail-to-rail output and wide common-mode range up to 40V provide significant design flexibility in various power rail configurations.

Applications

Getting Started

To evaluate this part, use the INA186EVM evaluation module which supports multiple gain variants. Ensure the shunt resistor is placed as close to the amplifier pins as possible and use Kelvin sensing connections to maintain measurement accuracy. The device requires a supply voltage between 1.7V and 5.5V for operation.
